1. General Drinking Water System Information
1.1 Where does the water come from?
The Cities of Mississauga and Brampton and the Town of Bolton, a population of approximately
1.3 million people, obtain their drinking water from Lake Ontario. Raw water from the lake is
pumped into two surface water treatment plants, Lakeview Water Treatment Plant (WTP) and
Lorne Park Water Treatment Plant (WTP), from intake pipes located up to two kilometres off
shore. The Lakeview and Lorne Park plants are owned by the Region of Peel and operated by
the Ontario Clean Water Agency (OCWA). Each year, the plants produce approximately 204
billion litres of water. A portion of water produced is also pumped into York Region. Both
plants are classified as Class IV systems.
Distribution System/ Storage Facilities
The distribution system carries water from the plants to the Cities of Brampton, Mississauga and
Town of Bolton through a series of pipes ranging in size from 350mm to over 1200mm in
diameter.
The South Peel water distribution system consists of 4,109 kilometres of water mains, 40,934
mainline valves, 24,907 fire hydrants and 299,856 water services.
(2010 - South Peel Water Distribution System)
There are a total of 12 reservoirs, 4 elevated tanks, and 2 standpipes in Brampton, Mississauga
and Bolton that hold and store water.
Some of the maintenance activities performed at the South Peel distribution system include:
• water main break repairs
• hydrant maintenance and repairs
• valve maintenance and repairs
• water service line installation/replacement/repairs, and
• customer service calls (water quality/quantity, turn off/on, pressure testing, etc.)

2. How is Water Treated?
2.1 Lakeview Water Treatment Plant
(Drinking Water Works Number 210000568)
Figure 1: Lakeview Water Treatment Plant
The Lakeview Water Treatment Plant serves the Eastern sections of Mississauga and Brampton,
and the community of Bolton. Operated as a conventional water treatment plant, Lakeview WTP
also has an advanced treatment train consisting of ozone, biologically activated carbon
contactors (BACC) and membrane filtration.
7

Conventional Treatment
Conventional treatment consists of the following steps: coagulation, flocculation, sedimentation,
filtration, and disinfection.
Ozone, Biologically Activated Carbon Contactor and Membrane Filtration (OBM) Treatment
The OBM treatment process consists of ozone, biologically active carbon contactor treatment
and membrane filtration.
(Please refer to Figure 2 below for the Lakeview Water Treatment Plant Process Diagram)
The Western parts of Mississauga and Brampton are serviced by the Lorne Park Water
Treatment facility. Several water mains link the two areas, allowing water to transfer from either
east to west or west to east.
The chemicals used at the Lakeview Water Treatment Plant over the reporting period were
aluminum sulphate (Alum), chlorine gas, hydrofluosilicic acid, polymer, sodium hypochlorite,
sodium hydroxide, sodium bisulphite, citric acid, and ozone gas.
Aqua ammonia is applied at the Airport Road Pumping Station only, to supply chloraminated
water to York Region.

To ensure an adequate supply of safe drinking water to an increasing population, in 2009,
construction began to enlarge the plant’s capacity to 500 million litres per day. The upgrades to
the plant include installation of modern, state-of-the-art, membrane filtration and an ultraviolet
(UV) light treatment system to inactivate pathogens and control the tastes and odours
occasionally found in the water.
Every effort has been taken to minimize impacts by implementing a design that uses the existing
footprint of the plant.
The chemicals used at the Lorne Park plant during the reporting period were acidified aluminum
sulphate (Alum), aluminum chlorohydrate (ACH), hydrofluosilicic acid, sodium hypochlorite
and sodium bisulphite.

2.3 Conventional Water Treatment Process Description
Lake Ontario is the source for the South Peel Drinking Water System. As the
lake water enters the intake, it can be chlorinated. The chlorine kills bacteria and
prevents zebra mussels from growing in the intake pipe and obstructing the flow.
As the water enters the treatment facility, it passes through the travelling screen.
The screen prevents items such as fish, sticks and aquatic plants from entering
the treatment facility and damaging equipment.
Low lift and backwash pumps are located in several pump Stations.
Low lift pumps draw the lake water into the treatment plant.
Coagulation assists with the removal of turbidity and suspended matter (particles) in the water.
A coagulant (Alum or ACH) is added to the water. The rapid mixer thoroughly mixes the
coagulant with the water to help form sticky particles.
13

Flocculation is the process of slow mixing that helps the sticky particles collide with each other,
forming larger and heavier particles called floc.
In the sedimentation process, floc particles are removed from the
water by inclined plate settlers. The water is slowed down in large
tanks to allow particles to settle to the bottom. The settled solids
are removed and transferred to the wastewater treatment facility.
Filtration removes remaining particles and chlorine-resistant bacteria and reduces the levels of
compounds that can cause tastes and odours. The water travels through layers of granular
activated carbon, sand and gravel. Water starts at the top of the filter and moves down by
gravity.
When needed, the filters are backwashed (cleaned). Clean water
is pumped up and through the filter media, in a reverse flow,
lifting and flushing out the floc particles that have accumulated in
the filter. The backwash water is treated in the backwash
treatment facility prior to being discharged into the lake.
The process of disinfection destroys harmful disease-causing organisms such as E. coli and
Giardia. Chlorine is the most common disinfectant used in water treatment.
14

Fluoride is added to the finished water to prevent cavities in our teeth. The finished water is
then stored in a reservoir and distributed into our communities through a series of pumps and
reservoirs.
Diesel-powered generators provide auxiliary or standby power for the facility. Standby power
ensures we can provide water in case of an emergency such as a massive power failure.
The water flows through water mains to houses, apartments, and schools, commercial and
industrial premises.

2.4 Ozone, Biologically Activated Carbon and Membrane (OBM) Water Treatment Process
Description
Low lift pumps draw water from Lake Ontario into the treatment plant.
Ozone gas is then bubbled through the water in the Ozone Contactors. Ozone kills
bacteria and also helps to break down substances that cause tastes and odours so that
they are more easily removed in the next treatment step.
The water then passes into the Biologically Active Carbon
Contactors (BACC). These specially designed contactors remove
the biodegradable organic matter produced by the activity of the
ozone process. The BAC contactors are very good at adsorbing
organic matter from the water and this removal process keeps the water stable after treatment by
minimizing re-growth of bacteria in the distribution system.
In the next treatment process, water passes through the Membrane Ultra Filtration system.
These are specially designed water filters with very small pores that the water is pulled through.
The membrane filters are so efficient that they are capable of
removing microorganisms and producing water with very little
turbidity.
16

Filtered water is directed to the Weir Box. The weir box stores water and is also the location
where chlorine and fluoride are added.
Treated water from both the conventional treatment and the OBM treatment processes flows by
gravity into the water Storage Reservoir.
The water must remain in the storage reservoir until adequate disinfection has occurred. Water
leaves the reservoir by way of High Lift Pumps and enters the distribution system.
17

3. Ontario Drinking Water Compliance Information
Drinking water quality in Peel is regulated by the Ontario government through the Ministry of
the Environment (MOE). The Ontario drinking water legislation sets requirements for municipal
system owners with regards to operation, level of treatment, sampling and testing, licensing of
staff and water quality notification.
3.1 Annual Water Quality Reports
To comply with the Ontario drinking water regulation under the Safe Drinking Water Act, 2002,
the Region of Peel prepares Annual Water Quality Reports providing information on quality of
water supplied and a Summary Report regarding the operation of the drinking water systems.
The Summary Report under Schedule 22 of Ontario Regulation 170/03 includes a statement of
compliance of the Region of Peel’s drinking water systems with the terms and conditions of the
regulations under the Safe Drinking Water Act, 2002, and a summary of the quantities and flow
rates of water supplied. This report is made available to Regional Council by March 31 of each
year.
The Annual Water Quality Reports and Summary Report are made available to the public to
ensure Peel consumers are kept informed. Each year, the reports are posted on the regional web
site and electronic or hard copies may be obtained upon request.
The Region places an ad in the local newspapers to inform its consumers about the availability of
the Annual Water Quality Reports.
3.2 Sampling and Testing
In accordance with the drinking water legislation, drinking water systems are required to monitor
their water quality to ensure it meets provincial standards.
18

Peel regularly samples and tests raw, treated and distribution system water for a number of
microbiological, chemical and radiological parameters. The Region has always had an extensive
water sampling and monitoring program to better understand the quality of source water, ensure
effective treatment processes, and to diligently monitor and protect the drinking water supply.
Sampling and testing is conducted by trained and qualified operators, who collect water samples
from various sampling sites throughout the Region and immediately test them for first water
safety indicators. Samples are also collected for laboratory analysis for more than 150 health
related and aesthetic parameters.
The Ministry of the Environment (MOE) requires that all drinking water testing laboratories be
accredited by the Standards Council of Canada (SCC) based on proficiency evaluation conducted
by the Canadian Association for Laboratory Accreditation (CALA) as well as licensed by the
MOE for all drinking water tests performed.
Peel operates its own laboratory for chemical analyses and also subcontracts analytical testing to
other area laboratories. All laboratories used by the Region are accredited by the SCC, licensed
by the MOE, and adhere to strict drinking water sample collection, handling and transport
protocols and procedures.
3.3 Licensed Operators
All treatment plant and maintenance operators and technical staff have appropriate Water
Treatment, Water Distribution and Water Quality Analyst certification, as required by Ontario
drinking water legislation. The training and certification program ensures that all operators are
certified to industry recognized standards. Peel has established a continuing education program
for all staff responsible for operating drinking water systems. This helps operators to gain
knowledge of the latest treatment technologies and advanced processes and to effectively
maintain system water quality and quantity.
19

3.4 Water Quality Notification
In compliance with the regulatory requirements, Peel reports every adverse water quality event to
the Ministry of the Environment and Ministry of Health and immediately initiates corrective
action to address the potential problem. Peel has established a notification protocol for reporting
of adverse water quality events and makes these reports and data publicly available in the Annual
Water Quality Reports.
4. How well did we do?
4.1 Operation
To protect the health of the public and to ensure consumers receive clean and safe water, the
Ministry of the Environment (MOE) has established the Ontario Drinking Water Quality
Standards (ODWS). These standards are set to ensure the water is free of disease causing
organisms and hazardous chemicals. In 2010, the Region monitored water quality by
undertaking over 85,000 process samples and tests to ensure a safe and clean water supply.
Appendix A provides a full summary of the water quality test results.
The Region of Peel is proud to report that for the year 2010, all drinking water samples met
ODWS. The MOE performs annual inspections on all municipal drinking water systems. Based
on the inspection findings, the MOE issues score cards. The score is based upon the questions
posed by the Ministry Inspector during each inspection. The South Peel drinking water systems’
(Lakeview and Lorne Park) overall performance is excellent, and for the past three inspection
years has been in the 90 th percentile.

5. Drinking Water Quality Programs
5.1 Municipal Drinking Water Licensing Program
The Ontario government has developed the Municipal Drinking Water Licensing Program
(MDWLP) in support of the Safe Drinking Water Act, 2002. The MDWLP requires municipal
drinking water systems owners to obtain: a Municipal Drinking Water Licence, Drinking Water
Works Permit, Permit to Take Water, an accepted Operational Plan, accreditation of the
Operating Authority, and a Financial Plan for the operation of the water systems. The Ministry
of the Environment’s (MOE) intent is to ensure a culture of commitment to quality, diligence and
dedication to consumers in the provision of drinking water.
Ontario Regulation 188/07 (Licensing of Drinking Water Systems) required the Region of Peel
to submit an Operational Plan and applications for the Drinking Water Works Permit and
Licence for each drinking water system under its authority by January 1, 2009. The Region of
Peel received Drinking Water Works Permits and Licences for each of its drinking water systems
in late November 2009.
In late September 2009, the Region of Peel received accreditation by the Canadian General
Standards Board (CGSB) for the systems audit conducted on the Operational Plan submitted.
Implementation of the Operational Plan began shortly after receiving accreditation and took
approximately 12 months to complete. The Region of Peel submitted an application for full
accreditation in September 2010 and anticipates the verification audit to be conducted in the
spring of 2011.
Ontario Regulation 453/07 (Financial Plans) required licensed drinking water system owners to
submit an approved Financial Plan to the Ministry of Municipal Affairs and Housing by July 1,
2010. The Water Division’s Financial Plan was endorsed by Regional Council in June 2010 and
submitted to the Ministry of Municipal Affairs before the required date.
25

5.2 Source Water Protection
In October 2006, the Ontario government passed the Clean Water Act, 2006, to protect drinking
water at the source as part of an overall commitment to human health and the environment. The
Clean Water Act came into force on July 3, 2007, with the release of regulations which enabled
the creation of multi-stakeholder Source Protection Committees.
The Clean Water Act, 2006, requires the development of drinking water source protection plans
to address drinking water threats to all ground water and surface water municipal drinking water
systems. Through continued collaboration with the Region’s Conservation Authority partners
and the Province of Ontario, Peel Region is completing a number of studies that will allow
Source Protection Committees to develop source protection plans for all the watersheds from
where drinking water is supplied. These Source Protection Plans will include policies that will
be designed to prevent contamination of drinking water sources. The Source Protection Plans
are scheduled to be completed by the end of 2012.
Groundwater Supply Protection
Peel was one of the first municipalities in Ontario to develop a Well Head Protection Area
program for its municipal wells. This program focuses on identifying and protecting areas that
replenish the municipal wells. As part of this program, the Region established a network of early
warning wells in the vicinity of its municipal wells. Water level and water quality monitoring is
conducted throughout the year at these early warning wells, which allows Peel Region to guard
its groundwater supply against potential sources of contamination. Further, the Peel Region has
undertaken studies for its municipal groundwater sources to meet the following objectives:
• Evaluate the vulnerability of municipal groundwater sources to surface or underground
contaminants;
• Identification of drinking water threats for each of the municipal wellheads
26

These studies were completed in 2010 and the results of these studies are being used to support
the development of watershed based Source Protection Plans and associated source water
protection policies.
Surface Water Supply Protection
In partnership with the Source Protection Committees for Source Protection Regions abutting
Lake Ontario, work is underway to assess the intake protection zones and drinking water threats
for the drinking water supplies from Lake Ontario. The Collaborative Study to Protect Lake
Ontario Drinking Water is a Peel Region led initiative that includes 19 municipalities, from
Niagara Region to Prince Edward County along the Lake Ontario shoreline.
The Collaborative Project includes the following components:
• Lake wide models to evaluate physical processes in Lake Ontario and enable the delineation
of intake protection zones for municipal water treatment plants.
• Watershed pollutant loading studies to evaluate pollutant loading to Lake Ontario.
• Identification of drinking water threats (chemical or pathogen) for each municipal drinking
water intake.
This study is on-going and is scheduled to be completed in 2011.
5.3 Private Well Abandonment Program
The Region of Peel implemented a Private Well Abandonment Program for decommissioning of
old, unused private wells in Caledon and rural Brampton and Mississauga. The Program intends
to gradually eliminate potential pathways of groundwater contamination in areas where
groundwater is the source for municipal drinking water. The Program is carried out on a first
come, first serve basis, with each well decommissioning request being evaluated prior to the
commencement of any decommissioning work. A total of 30 private wells around the Region
were decommissioned under this program in 2010.
Please visit the following link for more information on Peel’s Well Abandonment Program:
http://www.peelregion.ca/pw/water/water-trtmt/wellhead-abandon.htm
27

5.4 Water Main Renewal Program
The Region’s overall infrastructure is aging, requiring more investment in preventive and
planned maintenance. In response, Peel has established a comprehensive asset management
program, which includes water main assessment and renewal. The program is an ongoing plan
of upgrading Peel’s water main system to ensure long term integrity. The program involves
repair or replacement of existing mains to improve water flow, ensure good quality water and
upsize if required to meet future planning needs; all to provide a higher level service to our
consumers.
The Region determines priority of water main replacement based on the following factors:
1. Water main age
2. Water quality trends
3. Water main size and material type
4. Water main breaks and leakage history
5. Future municipal and city projects and road re-construction
6. Cost of replacement
The majority of the water main replacement projects are undertaken in partnership with road and
sewer renewal projects for improved cost effectiveness and minimized public inconvenience.
Using these criteria, Peel plans the water main renewal program in a financially responsible
manner.
In 2009, the Federal and Provincial governments announced an Economic Action Plan that
included an Infrastructure Stimulus Fund (ISF) to provide funding for construction-ready
distribution projects. Approximately 57.4 kilometres of water main in Peel were approved for
ISF funding. These water main replacements are targeted to be completed by March 31, 2011.

5.5 Community Lead Testing Program
Created in 2007, Peel Region’s Community Lead Testing Program fulfills the legislative
requirements under Ontario Regulation 170/03, Schedule 15.1. This program requires the
sampling and testing of drinking water of private residential and private non-residential locations
as well as distribution hydrants for lead.
Peel’s Community Lead Testing Program selects sampling locations based on the following
criteria:
1. Any homes or buildings built prior to 1960
2. Any plumbing connected to or suspected to be connected to lead service pipes
3. Any plumbing made out of or suspected of being made out of lead
The Community Lead Testing Program is conducted semi-annually between the dates of
December 15 to April 15 and June 15 to October 15 each year.
Every sampling period, the Region recruits volunteers of homes and businesses to participate in
the program. Sampling appointments are booked with volunteers over the phone. Upon
completion of the test results, the reports are mailed to their respective participants and
assistance is provided in interpretation of the data.
Testing performed in 2010 revealed mostly non-detected or low levels of lead in drinking water.
The majority of residences and businesses sampled met the standard for lead levels in drinking
water of 10 parts per billion. Results of this program aid in the asset management and water
main renewal program.
Peel welcomes the public to participate in our lead testing program. To request a free lead test of
your drinking water, please contact us at 905-791-7800, ext 4685 or visit our website:

5.6 Water Main Flushing Program
The Region of Peel’s water main flushing program is another element of the multi-barrier
approach to ensuring safe drinking water. The primary objective of the water main flushing
program is to maintain adequate chlorine residuals in the water distribution system. Under the
Safe Drinking Water Act, 2002, Ontario Regulation 170/03 stipulates the acceptable chlorine
residual range. Certified Water Operators measure and record the chlorine residual at each
flush. Flushing is conducted at locations where a low water demand may occur, such as deadends
and new subdivisions. Flushing frequency is greater in areas where the water demand is
lower. Flushing is also conducted following water system repairs and other situations where a
check of chlorine residual is warranted.
5.7 Hydrant Inspection Program
The Region of Peel hydrant inspection program fulfils a number of purposes. An annual
inspection is necessary to determine the sustained functionality of each fire hydrant and hydrant
branch valve. The flushing part of the inspection also serves to maintain chlorine residual at the
hydrant. Fire hydrant components that are in need of repair are identified during the inspection.
Deficiencies that affect the hydrant’s operability are handled on a priority basis.
5.8 Drinking Water Sampling Station Program
The Region installed a number of drinking water sampling stations throughout
Peel to improve drinking water quality assessment and monitoring methods and to
improve customer service. The installation of stations has decreased the need to
enter homes and businesses to obtain water samples and allow Peel to meet its
commitments to water quality with the least amount of impact to customers.

Water Safety Parameter Information
� Escherichia coli (E.coli)
Escherichia coli (E.coli) is a fecal coliform and can be detected using approved lab methods. E.
coli is present in fecal matter and prevalent in sewage, but is rapidly destroyed by chlorine. It is
a strong indicator of recent fecal pollution. Presence of E. coli bacteria in a sample of drinking
water signifies potentially inadequate treatment. Corrective action needs to be taken and
confirmatory samples collected.
� Total Coliform
Total Coliform bacteria are part of a family of bacteria called Enterics. Coliform bacteria grow
under the same conditions as disease-causing bacteria. That allows us to use them as indicator
organisms. Presence of coliform bacteria in a sample of drinking water signifies potentially
inadequate treatment and is unacceptable. Corrective action needs to be taken and confirmatory
samples collected.
� Heterotrophic Plate Count
Heterotrophic plate count (HPC) results give an indication of overall water quality in drinking
water systems. HPC results are used as a tool for monitoring the overall quality of the water
immediately following treatment and in the distribution system. HPC is not an indicator of water
safety but is used as an indicator of water integrity within the distribution system.
� Disinfection By-products
Disinfection of drinking-water is essential to protect the public from waterborne infectious and
parasitic diseases. Disinfection inactivates bacteria in the water and protects the water pipes
from any subsequent contamination during storage or distribution. The most commonly used
drinking water disinfectant is chlorine. The use of chlorine may lead to the formation of byproducts,
including trihalomethanes (THMs). THMs are formed when compounds left in the
water after treatment combine with the chlorine.

Possible Cause Suggested Solutions
• Chlorine getting combined with organics
• Chlorination of new water mains
• Effects of new plumbing
• Change of residency as chlorine
concentration varies from location to
location
• Algae that bloom in the lake in the summer
produce a metabolite called ‘geosmin’,
which causes musty/earthy odour
• Dead-end water mains or areas with low
water demand
• Poorly maintained hot water tanks
• Faucet aerators/screens and sink drains
• Air trapped in water due to water main
breaks, water temperature or pressure
change, plumbing work, construction work
in the area, water shut-offs
• Hot water tank temperature may be set too
high
• Copper in water due to copper plumbing
Change in water flow due to:
• Water main break
• Hydrant use
• Local Fire
• Dead ends
• Poorly maintained hot water tanks
• Flakes are scale caused by hardness
• Faulty or disintegrating hot water tank tubing
or lining
• Pink pigmented bacteria called Serratia
marcescens
• Airborne bacteria not known to cause disease
Chlorine is necessary to control disease-causing organisms.
To minimize the chlorine taste and smell in water;
• Fill a pitcher and let it stand in the refrigerator overnight
• Blend the water for 5 minutes or pour between containers
about 10 times
• Boil the water, let it cool down and then refrigerate
• Home plumbing may be flushed for a minute before water use
(especially in the mornings, after water stands in the lines
overnight)
• The algae are harmless and although the water may not be
aesthetically pleasing, it is safe.
• Clean faucet aerators and screens on frequent basis
• Hot water tanks should be flushed periodically (every 2 to 3
years) to remove rust and scale
• Refrain from flushing solids/organics down the drain; stagnant
wastewater in the drain may generate foul odours and
potentially plug the drain
• Run all cold water taps at once for a couple of minutes to flush
the lines and release the air
• Lower the hot water tank temperature if above 140F(60C)
• Run water for 30 seconds to reduce the effects of local
plumbing (metal concentration) prior to water consumption
• Keep fixtures dry and drip-free
• Open cold water faucets and flush water for 5 to 10 minutes,
until clear
• Refrain from doing laundry to prevent clothes staining
• Hot water tank should be flushed periodically (every 2 to 3
years)
• Can be reduced by frequent cleaning of faucet aerators/screens
and/or frequent flushing of hot water tanks
• Contact the hot water tank company
• Scrub surfaces with a brush
• Disinfect with a strong bleach solution
• Allow disinfectant to penetrate for 10-20 minutes
• Rinse

Frequently Asked Questions and Answers on Water Quality
� Is my water safe to drink?
To protect public health, the Ministry of the Environment has established the Ontario Drinking
Quality Water Standards (ODWS). These objectives help ensure that water used by the public is
free from disease-causing organisms, hazardous amounts of toxic chemicals and radioactive
materials.
� Why do we use chlorine?
Chlorine is used to kill bacteria, viruses and other organisms that can cause illness. We are
regulated on the amount we can add to the water as per the standards in Ontario Regulation
170/03. The standard states that we must maintain chlorine residual at a minimum level 0.05
mg/L and cannot exceed a maximum level of 4.0 mg/L.
� Is the water hard?
Hardness is typically dissolved calcium and magnesium in the water measured as calcium
carbonate. Upon heating, hard water has a tendency to form scale deposits or a white film and
can form excessive scum with regular soaps. Conversely, soft water may result in accelerated
corrosion of water pipes. The water in the South Peel system is considered to be moderately
hard.
� Should I buy a water softener?
The purchase of a water softener is based mostly on personal preferences. Soap suds are formed
more readily with soft water, therefore less detergent is used. The use of a water softener also
reduces the formation of hardness scale in pipes and hot water tanks. Some consumers do not
like the feel of soft water. For example, after rinsing you may still feel a soap film on your skin
if you used soft water.
41

� Why does the water sometimes look “cloudy” or “milky”?
Tiny bubbles of air in the water cause the cloudiness. Those bubbles may also cause the water to
appear white or foamy, similar to the appearance of water in a rushing stream. This does not
indicate any problem and clears when the water is left to sit for a few minutes. This is an
aesthetic not a health concern. If cloudy water does persist, please notify the Region of Peel so
that the matter can be investigated.
� Is fluoride added to my water?
Fluoride is added to the water supplied to the cities of Brampton, Mississauga and the town of
Bolton. The amount is regulated and is maintained at an optimal level that prevents tooth decay.
� Why is my kettle stained inside?
The presence of calcium and manganese in water will stain a kettle. When water is boiled,
calcium and manganese precipitate out of water and deposit on the element and inner surfaces of
the kettle. This does not pose a health risk. Staining can be prevented by regular rinsing with
vinegar or lemon juice.
� Why does the water sometimes look “rusty”, yellow or Tea-like?
Yellow water is a common occurrence. Excessive levels of iron in drinking water may impart a
brownish colour, often seen on laundered clothes, plumbing fixtures and the water itself.
Running your tap for a few minutes can clear the colour. No health risks are associated with this
discolouration. If you are experiencing problems and your neighbors are not, the hot water tank
or the pipes in your home are likely causing the problem.
42

� Does the Region knock on the door to test water or leave a bottle to fill?
Some of our water programs require testing on private premises, such as residential homes or
businesses. This would only be done by the Region with prior arrangements with the owner or
tenant of the premise. Based on the stringent provincial guidelines, drinking water samples must
be collected and handled by qualified persons and analysed at an accredited laboratory; therefore,
Peel staff would not leave a bottle at the door requesting a sample of water for testing, and will
always carry a Region of Peel identification card.
There are many responsible home water treatment businesses that offer products that live up to
their claims. Unfortunately, some companies and salespersons resort to grabbing the public’s
attention and misinforming them about the safety of the municipal drinking water supplies in an
effort to sell their products.
To ensure that you are informed about the water quality in Peel and less likely to become a target
of a company trying to sell you costly and inappropriate water treatment equipment, or if you
have questions or concerns, please contact our Water Quality Team at 905-791-7800 ext 4685 or
via e-mail to WaterQualityInquiries@peelregion.ca
� Why is lead sometimes present in water?
Lead is a metal that can dissolve in water. Traditionally, lead compounds were used in plumbing
fittings and in solder to join pipes together in water distribution systems. If water stays in a
piping system that contains lead for long periods of time, lead may dissolve into the water.
� How does lead affect my health?
